Chinese barbecue deli restaurants, called siu laap and sometimes called a "noodle house" or mein ga, are generally low-key and serve less expensive fare such as wonton noodles (or wonton mein), chow fun (stir-fry rice noodles), Yeung Chow fried rice, and rice porridge or congee, known as juk in Cantonese Chinese. They also tend to have displays of whole pre-cooked roasted ducks and suckling pigs hanging in their windows, a common feature in most Chinatowns worldwide. These delis also serve barbecue pork (cha siu), chicken feet, and other Chinese-style items less welcome to the typical Western palate. Food is usually intended for take-out. Some of these Chinatown restaurants sometimes have the reputation of being "greasy spoons" and reputation for poor service. Vietnamese immigrants, both ethnic Chinese and non-Chinese, have opened restaurants in many Chinatowns, serving Vietnamese pho beef noodle soups and Franco-Vietnamese sandwiches. Some immigrants have also started restaurants serving Teochew Chinese cuisine. Some Chinatowns old and new may also contain several pan-Asian restaurants offering a variety of Asian noodles under one roof.
